into three categories developing an ml model where java isn t competitive and is unlikely to become top of the class any time soon developing an ai centered product where java is well positioned and will become stringer soon but does this category matter in the long run and adding ai based features to larger projects where java is already very good and will only become stronger thanks to valhalla s value types panama s ffm and vector apis and babylon s code reflection 2024 07 04 why update data oriented programming to version 1 1 post dop a review of data oriented programming version 1 1 what

preview that was present in jdks 21 and 22 let s discuss why the feature was removed probably not for the reasons you think what a new proposal could look like and when we may see it 2024 06 20 jdk 23

separate operations from data data oriented programming v1 1 post dop pattern matching data oriented programming guides us towards a separation of data and operations operations should be implemented in dedicated subsystems using pattern matching over sealed interfaces to pick execution branches and deconstructing records to implement domain logic 2024 06 05 make illegal states unrepresentable data oriented programming v1 1 post dop data oriented programming focuses on modeling data as closely as possible and a guiding principle for achieving that is to ensure that the software can not represent illegal states that can be achieved with good type design or with constructor checks plus tests 2024 06 03 model data the whole data and nothing but the data data oriented programming v1 1 post dop data oriented programming dop centers around modeling data as closely as possible and so a core principle of dop is to model the data the whole data and nothing but the data this goal is best achieved with a mix of records and sealed types as well as some programming practices that may seem odd to the object oriented developer all of which is explored in this article 2024 05 29 model data immutably and transparently data oriented programming v1 1 post dop records to model data immutably and transparently is one of the four principles of data oriented programming in this article we explore why immutability and transparency are important when modeling data and how to use java s features particularly records to achieve that 2024 05 27 data oriented programming in java version 1 1
